no

Key result

Parameter:

other: oxygen balance

Value:

-170.19

Remarks on result:

other: the calculated oxygen balance was above the trigger value of -200

Key result

Parameter:

other: exothermic decomposition energy

Value:

182.17

Remarks on result:

other: The curve displayed one exothermic peak between 300 and 350 °C with an energy release of 182.17 J/g. As a result, energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Screening evaluation:

Analysis of the molecular structure for Disperse Red 302 revealed, that no such chemical alert structures are present in the molecule. Calculation of the oxygen balance according to the above mentioned formula is -170.19 and therefore above the trigger value of -200.

 

Determination of the exothermic decomposition energy:

The curve displayed one exothermic peak between 300 and 350 °C with an energy release of 182.17 J/g. This peak is considered to represent substance decomposition energy. As a result, energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Interpretation of results:

GHS criteria not met

Conclusions:

Disperse Red 302 is considered to be non-explosive.

Executive summary:

Explosive properties associated with Disperse Red 302 were assessed using the screening procedure as described in the CLP-Regulation, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3, in "Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria" and in the "Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3". Analysis of the chemical structure revealed no alerts for explosive properties. The calculated chemical oxygen balance was above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required. Disperse Red 302 is considered to be non-explosive.

Description of key information

Explosive properties associated with Disperse Red 302 were assessed using the screening procedure as described in the CLP-Regulation, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3, in "Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria" and in the "Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3".

Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required. Disperse Red 302 is considered to be non-explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

As the Disperse Red 302 has been considered to be non-explosive based on the expert statement, hence, does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
